The innerend of the clip'flS extends through anopening provided in the cap and the extremityis bent flat against theinner wall of the cap, so that the end of the clip-'is substantiallyU-shaped, as indicated at 19 in Figure 2 of the drawings. In order tosecurely retain the clip in place there is provided a holding .member20. n' This member isy formation and isclosed at one end, its outerdiameter being such as to provide a snug fit within the cap. vThe member2O is provided with a groove extremity of the 'clip 18. An auxiliary"cap 22 lits over the end of the cap 12 and'carries a threaded stud 23.This stud passes through an opening' provided in the cap` 12 and has`threaded engagementwith the end of the holding member 20, so that thelatter will securely hold the clip in place.V

If desired, the clip 18 may be dispensed with and a screw eye ,24 may besubstituted for the threaded stud 23. kpasses through the auxiliary cap22. and the cap 12 and threadedly engages the holdingl member 20, asshown in Figure 4..
